My inw-ntion rrlatrs to improrrmrnts in rnt't'igt-rator display casr: myobjrrt hoing to providta roustrurtion in whirh a rirrulation of air inulintainrd in szm'li a nmnnor that tho temperature is krpt low andapproximatrly uniform throughout the rntirn casr. notwithstaiuling thr'fart that. in a dotior of this: rharart r1 thr ice is located aronaitlvrablo (listanor from. and orrupirs a surfm'r slightly hr-lowthat ol" the portions of tho case in which the articles to be displaycdare located.

In my improved raso tho ice is loratrd in tho ventral portion of the051%. thr rompartmonts or portions of tho ollambor orrnpird hy thrartirlos. rxtrndin on oppor ito sidn thrrrof and for a 'Ottfihfil'tlllltdistanrr hryond tho rompartmrnt or location in whirh thilt't is loratrd.Tn (390R of this character it is impossible to obtain tho br-stttfitllts'. namrly, to ltrrp tho trmprraturr low and rquablo throughoutthr out'iro rhnmlmr. with out SPt'titll provision for obtaining arirrulation of air from tho rontral portion of thr rhambrr whrrr the loois lorutrd.'to filo oppositr ends thrrrof. and back aga in to till 100.rompartmout.

This rirrulation I obtain by sparing the (ltl7 pan in much andrompartmrnt or in portion of the chamber a'djarrnt the crntralrompartmrnt when tho ior iii loratrd. from tho floor proprr of tho casr,thus t'ormim a spare uudrrnrath the drip pan throng] which air may('ll't'llltllfi brlow thr mu. thr outrr rxlrrmity of this spare in rarhmstnnro. communirating with a \Tl'llttlll) arraugrd spare hrtwrrn thooutrr rnd wall tho raw and an intvrior partition aparod from lltt rudwall. and wrtoratrd at suit.- ably olovatrd points. to allow tho ai:lftor riroulatiug lwlow .tho drip pan and u wardly through the paoo at"tho and of t (use. to pass into the upper portion of the rodvonumrtnwut. Again. this air in turn will brromr roolod and moredownwardly, aftrr which it will again'rnter thospaco bc-.. low tho drippain. in this mannrr the con stant rirrulation of air through the rcfrigrrating munlmrt-uu-nts of the (one is maintainrd.

Lrt tlu' nunuu'al 5 rlrsigznat -my improvml display vase considrreti inits ontiroty and ronsisting of top, bottom, ond and side wallsim-losinga rhambor having a central portion or rompartment 6 and two-end portionsor rompartmruts 7 arran-god on oppositr-sidos of and in t'omuumirationwith lhr ('rulral rompartnu'nt. it will l)? unrlrrstood that thedivisions or planfla of drmarration lwtwovu the ventral rompartm'cnt tiand the 0nd rompartmruts 7 arr ihiag'inary rathrr than real.Nm'rrthrlrsn tho term rompartnwnt is brlirvrd to hr proprr andt'rltainly tho most ronvrnivnt trl'm that run hr rmployvd in dysrribingtho strut-turn. Tn tho bottom of the vontral '(tlttlllttl'ltlleltl fl islUttllllL a pan H whirh slopes downwardly from its onto-r (*(lgtH towarda rrntral openmo 1) from whirh loads a short drain pipe or nozzlp it)through which thr wutqr rrsultiugz from the melting. of tho irr rake 12may paw. ,Thr outer rdgoo of this pan are slightly hrlow tho upperaurfarr of' tho drip pans lit arraugrd on oppoaitr sides of the ire pan,those drip pans bring spaced from thu 'l'iottom proper [4 of the rasr,in am suitable nmnnrr. This s tiring of the drip pans: from tho bottomof tlio (also. learns apart-s 15 hrlow thr drip pans through whirh theair may (il'tlllttlt from the bottom of tho routral rompartmrut 6 asindiratod by tho arrows iii Fig. 2. As shown in the drawing. oat-h drippan 13 has the innrr rdgr of its bottom bout slightly downwardly asshown at 16 toward the bottom of the ice where it connnoncos anothercircuit.

an. a space or opening 17 being, however. oft to allow the an toeuterthe spare 17 and circulate underneath each of the dri pans. Theouter eittremity of t'ttt'll spare l oommunicates with the bottom of avertioally disposed spare 18 which is formod between the end 'wall 19 ofthe ease and an inner partition 20 which is spaced from the end wall inany suitable manner. The upper portion of the artition 20 is providedwith )orl'orations 1 through whioh the air alter oirctllating upwardlyinto the upper portion of each space 18, may return to the ohamhor ofthe ease, this circulation hoiug imlioatod bv the arrows in Fig. 2 ofthe drawing. This air. after returning to the case. will again beoomesulliciently cooled to oauso it to fall, after which it will again enterthe inner extremity of the Spttt'l 15. when its oirculatory action willbe repeated. In this way the constant ciroulatiou of air is kept up fromthe bottom of the ire oompartnn-nt, outwardly and upwardly. and lllfl'hinto the upper portion of each end compartment. thence through the endcompartment to the center eoln nu'tmont. and a ain downwardly into thebottom of the iie eonnmrtnn-nt. l 'rom this it will he llnder tood thatthere will be no dead air spaces within my improved ease Binco there isa constant circulation of the air from the center or ice i-ompartment,onlwnrdly, upwardly, and baek through the up per portions of the endcompartments into the center compartment.

Normal circulation through the provision Chambers, will not heinterfered with, while heat taken up at the endsof the case within thevortiral apnoea will be more quickly and thoroughl neutralized.

'lu-n dr ired the openings ll may be olo-od l1) pivoted members .22.

Having thus dosorihod my invention, what I olaim lat refrigeratordisplay ease having a uh- .wlantially. horizontally arranged bottom. acentral ieo oonumrtmont and an artiole-eontaining rmn|u|rtnlrlltarranged on each side thereof. the bottom of the ire compartment beinginclined toward a central drain opening. the bottom of eachartit'lo-oontaining wtn mrtment being provided with a drip pan which isdownwardly inclined from its outer (Xllt'llIil V toward the iceoompartmout. the bottom of the latter being slightly lower than theupper surface of the drip pan. each drip pan being spared fr m thebottom roper of the WIN. thus forming a bottom air space whit-h i inronnnunication at its inner extremity with the lower part of the icerompartment. each article 'containing eompartmont having at its outerextremity a vertical partition spaced from the end wall of the ease toform a vertically disposed air space which is in communication at itslower extremity with the outer extremity of the said bottom air space.the upper portion of tho \ei'tiral air spare being in eonnnuni cationwith the upper portion of the tltljaeont articlo-rontainingcompartnn-nt.

In testimony whereof I allix my signature, in present-e of twowitnesses.
